yet... when i just change the frecuency from 6000 ( with docp profile) to 6200mhz the sistem post without making a hard reset and aparently working fine
Double check to make sure that it's actually running at 6200MT/s, and that the memory controller clock is at 3100MHz. If you want to check in CPU-Z, you just want to make sure the DRAM frequency and the NB Frequency are 3100MHz (in the memory tab). If the memory controller clock (NB Frequency, also called UCLK in HWInfo and Ryzen Master) is half the DRAM frequency, go into the BIOS and change the MEMCLK/UCLK divider to UCLK == MEMCLK rather than UCLK == MEMCLK / 2. If that causes the system to stop booting, drop the frequency down until it starts being able to boot in UCLK == MEMCLK mode as that will get you the best performance.

is safe to use it this way?
Yeah, it's safe. Nearly every kit rated at 5600+ will be able to do 6400MT/s with ease, and that kit is no exception. I'd want to run a memory stress test to be sure, as well as double check that the SOC voltage is below 1.3V, though it should be fine. Most Ryzen 7000 series CPUs can do 6200 with minimal effort, and yours seems to be one of them.

or i shall wait for another bios update to solve this incompatibility problem ?
I would try to update when the new BIOS revision comes out, it does sound like they broke the 6000MT/s memory ratio and odds are they broke something else.
